The 3D Concrete Printing process involves a computer-controlled machine that extrudes layers of concrete, one on top of the other, to build structures directly from a digital model. 3D concrete printing allows for more design freedom and can produce complex shapes and structures that would be difficult or expensive to achieve using conventional techniques.

Digital Design: The process begins with a digital 3D model of the structure, created using computer-aided design (CAD) software. This model provides the precise specifications for the printer to follow.

Concrete Mixture: A specialised concrete mix is prepared. This mix is often tailored to be flowable enough to be extruded through the printer nozzle yet quick-setting to support subsequent layers without deformation.

Printing Process: The Contec 3D printers large robotic arm follows the digital model’s instructions to extrude the concrete layer by layer. The nozzle moves in precise patterns, depositing the concrete in successive layers to build up the structure.

Layering: Each layer is printed in a predefined sequence. The printer ensures that the layers bond together properly, resulting in a solid and cohesive structure.

Speed: 3D concrete printing can significantly reduce construction time compared to traditional methods.

Cost-Effective: It can lower labour costs and reduce material waste.

Design Flexibility: Allows for the creation of complex and custom designs that would be difficult or impossible to achieve with conventional methods.

Sustainability: The process is more environmentally sustainable, as it uses materials more efficiently.

Contec walls can be finished using many modern and traditional applied finishes to serve different purposes. The choice of finish will depend on factors such as the location of the wall (interior or exterior), the desired look, and the environmental conditions the wall will face. Some common finishes that can be applied to Contec walls are:

· Paint

· Plaster

· Texture Coast

· Tiles

· Secondary cladding

Contec walls act in the same manner as traditional wall systems and there is no need for bespoke detailing to install roofs or windows.

Contec walls achieve sustainability by reducing material waste, utilising recycled materials, optimising design for efficiency, and minimising energy consumption both during construction and during the entire life cycle, all of which lower the environmental impact compared to traditional construction methods.

Contec walls are fire and acoustically tested and rated to withstand Australian conditions.

Contec walls are design to be water resistant and can be designed to be fully waterproof, for use in water retention applications or to save guard against events of flooding.
